Looking to buy this 36 @ 4400.00 brand new 5 hours and wanted to see if anyone has experience with this mower?

1. How are they on bad turf(bumpy, mole holes), I guess what I mean is on a walk-behind with pistol grips you can push down a little and work out thos bad spots that normally scalp really bad.
How can you do that with the stand up versions.
